Strategies for remediation of soils contaminated with mercury (Hg) are important and necessary. Several bacterial species interfere with biogeochemical cycle of mercury and are potential tools in bioremediation and/or phytoremediation programs. These bacteria are resistant to mercury and the main mechanism of resistance is mediated by proteins codificated by operon mer. This study aims to determine the level of resistance to mercury of endophytic bacteria and detect the presence of merA gene
